    Pre-Separation Air Filtration System
    This time-saving technology boosts the efficiency of the engine’s filter system, doubling the time between air filter cleanings. Air drawn into the engine is first separated via centrifugal force, ejecting the heavier dirt particles before being routed to the air filter. This pre-separation means less dirt to be captured by the air filter, resulting in less frequent cleaning and maintenance.

Important Information
WARNING! The occurrence called “kickback” can cause serious or fatal injury. Always read the instruction manual carefully before using your saw. STIHL uses a green and yellow color-coding system to help you select a powerhead, bar and chain combination that complies with the kickback requirements of ANSI Standard B175.1 (gasoline-powered saws) and §30 of UL 1662/ ANSI Standard B175.1 (electric chainsaws). Ask your STIHL dealer about safe operating procedures and the advantages of the STIHL Quickstop® chain brake, STIHL Quickstop® Plus (Q) additional chain braking feature, STIHL reduced kickback bars and STIHL low-kickback saw chains.

STIHL recommends the use of green reduced kickback bars and green low kickback chains on all STIHL chainsaws.
* The actual listed guide bar length can vary from the effective cutting length based on which powerhead it is installed on.
Note: STIHL recommends use of fuel with no more than 10% Ethanol content. Using fuel with greater than 10% Ethanol content may cause damage to your equipment and may void your STIHL warranty. Learn More…

Are You Ready for a STIHL?

MS 271 FARM BOSS® is rated 4.7 out of 5 by 427.
Rated 5 out of 5 by from Great mid range saw that keeps up the Stihl and farm boss reputation Had this saw for about a year and I put it threw its paces last fire wood season.i cut about 11 cords of hard wood with it and it's never slowed down or gave me any difficulty what so ever with general maintenance.it runs a 18" bar with ease and a 16" inch bar turns it into a beast.i have four Stihl saws ,the 271 is the most used out of all of them.from felling to limbing this is the saw that does it all.

Rated 5 out of 5 by from Very happy with the farm boss! I am impressed with the saw so far. I completed the engine break in as instructed and the saw runs better and better every time I use it. It cuts through 16in oak logs at half throttle with ease. The saw is great on fuel also, it took lots of cutting to go through the first 3 tanks of fuel. My only disappointment is that it did not come with a 20" bar on it. Mine came with an 18" bar but almost all other ms271 farm boss saws I have seen come with a factory 20" bar. I am very pleased with the saw and I would definitely recommend it to anyone seeking a good all around saw.

Rated 4 out of 5 by from This is one get it done machine. This 271 Farm Boss kicksbottom. Sorry if you cant use my review but it does kick bottom, be proud Stihl you produced a modern tool worthy of you name. The plastic housings......ask me next year about them, I will tell you how they held up. I am an Aviation, Jet Turbine Mechanic...I am hard to please and I hold no quarter in telling you exactly how I feel about your product. I have owned some of your failures....now I own a chainsaw that seems, so far, to hold to your claims of performance. I have recently purchased one of your FS 38 weed trimmers.....the power to weight ratio is superb.....let ya know what i think of it next year.

Rated 5 out of 5 by from Awesome saw! I made a few mistakes and bought a few other cheaper brand names. I am glad I made the choice to buy a Stihl! Best I have ever used and the company I bought it from ....Tops

Rated 5 out of 5 by from It's a great saw I grew up on a farm and have cut wood all my life, have used all kinds of saws over the years. My wife bought me the MS271 Farm Boss with a 20" bar for Christmas. First thing I did was drop a big thirty five foot locust tree. It ate it up! Starts fine - oils great-no issues. I bought a second chain for it and cut all kinds of fire wood with it, that size is a little big for small trimming but just right for most jobs...I couldn't be happier with it.
